Smoked mackerel on a slice of Danish rye bread is a real summer treat for me. My mom always bought smoked mackerel or herring for our weekend lunches in the summer period. And we all loved it. So I was very excited, when I finally found smoked mackerel from Ducktrap River of Maine(not smoked pepper mackerel) at my local Whole Foods. Of cause this is not the same as getting a freshly smoked whole mackerel, but its pretty close in taste, but a bit firmer in texture.
